It was also slang for a Morse signaller.
Speaking of which, I came across 'zogging' in a book about WW2 last week
and have just been googling its etymology. 'Zogging' was airforce slang
for sending Morse by swinging your arm over the side of a string bag -
slow and long for dash, fast and short for a dot. A WW1 sky pilot
supplied the answer:
THE following soliloquy was overheard the other morning from one
of the Royal Corps engaged in the daily task of zogging it off:
"The greatest war the world 'as ever seen! And wot's a Marine
doin'? Cleanin' paint-work!"
(_ Grand Fleet Chaplain's Note Book_, 1916.)
That confused me at first. Was the guffy waving his arms about in
irritation? Or was this a different 'zogging', perhaps related to
'soaking' in some way? No. It seems that _Zog_ was a well-known cleaning
fluid. Slogan: 'Zog it off!' It was particularly efficacious on grubby
paint-work but could also be used on baths, mirrors and china. _Pink
Zog_ brought a sparkle to your silverware. 8d a tin at all good grocer's
and ironmonger's.
Sending Morse by swinging your arm must have looked like you were
polishing the side of your crate.
I think I'll celebrate by squirting a mouldy at some medical comforts.
